DWR例子2--调用后台带参数方法

其他代码与例子1一样，故只提出不同代码

前台页面：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
	<head>
		<title>testDWR.html</title>

		<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
		<meta http-equiv="description" content="this is my page">
		<meta http-equiv="content-type" content="text/html; charset=UTF-8">

		<!--<link rel="stylesheet" type="text/css" href="./styles.css">-->
		<script type="text/javascript"
			src="dwr/interface/helloWorld.js"></script>
		<script type='text/javascript' src='dwr/engine.js'></script>

		<script type='text/javascript' src='dwr/util.js'></script>

		<script type="text/javascript">
		function getStr(){
			var name = $("tx1").value;
			helloWorld.getStr(name,function(msg){
				alert(msg);
			    $("sp1").innerHTML = msg;
			});
		}
		
	</script>
	</head>

	<body>
		<input type="text" id="tx1">
		<input type="button" value="调用后台getStr(String name)方法" onclick="getStr()">
		<span id="sp1"></span>
	</body>
</html>

?后台代码

package com.wepull.dwr;

public class HelloWorld {
	public String getStr(String name){
		System.out.println("执行了 getStr(String name)方法");
		return "hello: "+name;
	}
	
}
